I'll assume that you want mirroring (RAID 1). In diskdrake, select the first disk, toggle to expert mode and create a partition, choosing linux raid as the type. Now do the same using the same size on the other disk.
Select the created partition and click on the "add to raid" button. Choose new and accept the defaults. Select the other disk and add the other partition to the same raid disk. Now you'll have a raid tab. Select that and you'll see md0 has been defined. Select that and decide on a file type and mount point. Repeat until done, or totally confused. Copying home across can be done by a simple: cp -Ra /home /mount-point Then adjust /etc/fstab to mount the raid device at /home. Copying the root file system is more involved and assuming that you don't currently have a separate /boot partition, it is not feasible to move this onto a RAID without re-installing AFAIK. How about leaving / intact and creating new separate RAID partitions for /var and /usr? That means leaving the existing disk in the machine as well, but will avoid the re-install scenario. HTH Brian
